This video is about types or kinds of subordinate clause. A subordinate clause can be categorized into three: noun clause, adjective clause and adverb clause. We get a noun clause by asking question to the verb of the principal clause with what or whom. We get an adverb clause by asking question to the verb of the principal clause with ‘when, where, how’. An adjective clause comes after a noun which is qualified by that very clause. Thanks for watching the video.
